well there is the build turret, SP, SP, Reactor and that way you can have a turret along with gunner, then barracks 4th which could be bad so im not sure if this would work for you but I have tried it against arby and it has worked it migh tnot be the same against brute, but make Flashbang flamers make sure they are flashbang and makes more flamers then hogs by alot in fact dont evne make alot of hogs at all and try to get flashbang flamers with a turret up and jsut spam them. I dont know if you are attacking the brute cheiftain or the brutes but go for the brutes and kill all of them and then go for the cheiftain then he is screwed if he trys vortexing your flamers then try and hug his brutes so he will do damage to them to.

hope this helps I dont know how I normally stop them I just do.
